Confirmative demonstration of culturability and survival potential of Bacillus spp. SUBB01 cells upon heat shock. Cells were grown aerobically as stated earlier, and aliquots were removed at 24 h for spot tests. A progressing decline in bacterial growth was observed at 53 °C and the complete abolishment of cells was found at 54 °C after 24 h of incubation period in both nutrient agar media and Luria–Bertani agar media
